Ugo [173]

The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern.

<h3>What is the Y-5 molar pattern?</h3>
  • This is a distinctive type of molar teeth pattern found in apes and hominoids.
  • In this, 5 cusps or raised surfaces are present on the grinding surface of teeth, roughly forming a Y- shape. Therefore, this is also known as Y-5 pattern.
  • Whereas Old world monkeys have only 4 cusps on their lower molars present in a bilophodont pattern.
  • A Y-5 molar is formed when the tooth is divided into different pieces which form the complete structure of the tooth.
  • In bilophodont pattern the tooth is divided into 2 symmetric sections.
  • The dental formula of apes is 2.1.2.3/2.1.2.3 i.e. 2 incisors, 1 canine, 2 premolars, 3 molars.

The substance dichlorophenyldimethylurea (DCMUDCMU) is an herbicide that inhibits photosynthesis by blocking electron transfer b
mario62 [17]

Answer:

No

Explanation:

During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.
